Nomogram for Predicting Postoperative Pulmonary Metastasis in Hepatocellular Carcinoma Based on Inflammatory Markers.

BACKGROUND: Uncertainty surrounds the usefulness of inflammatory markers in hepatocellular carcinoma (HCC) patients for predicting postoperative pulmonary metastasis (PM). The purpose of this study was to assess the predictive value of inflammatory markers as well as to create a new nomogram model for predicting PM. METHODS: Cox regression was utilized to identify independent prognostic variables and to create a nomogram that predicted PM for comparison with a validation cohort and other prediction systems. We retrospectively analyzed a total of 1109 cases with HCC were included. RESULTS: The systemic inflammatory response index (SIRI) and aspartate aminotransferase-to-platelet ratio index (APRI) were independent risk factors for PM, with a concordance index of .78 (95% CI: .74-.81) for the nomogram. The areas under the curve of the nomograms for PM predicted at 1-, 3-, and 5-year were .82 (95% CI: .77-.87), .82 (95% CI: .78-.87) and .81 (95% CI: .75-.86), respectively, which were better than those of Barcelona Clinic Liver Cancer and China liver cancer stage. Decision curve analyses demonstrated a broader range of nomogram threshold probabilities. CONCLUSION: A nomogram based on SIRI and APRI can accurately predict postoperative PM in HCC.

The association of serum IL-33/ST2 expression with hepatocellular carcinoma.

BACKGROUND: IL-33 is a multifunctional cytokine with dual functions. However, the clinicopathological and prognostic significance of IL-33 in cancer patients, especially in patients with hepatocellular carcinoma (HCC), remains controversial. Therefore, we conducted a study of 565 patients with HCC and 561 healthy controls and performed a meta-analysis to quantitatively evaluate the above problems. METHODS: We collected blood from 565 patients with HCC and 561 healthy controls. ELISA was used to detect the concentrations of IL-33 and ST2 in the serum, and RT‒PCR was used to detect the levels of IL-33 and ST2 mRNA. Meanwhile, we collected comprehensive literature on IL-33 and the clinical characteristics of cancer patients retrieved from the PubMed, Web of Science and CNKI databases as of December 2022. An odds ratio (OR) with a 95% confidence interval (CI) was used to estimate the impact through overall and stratified analyses. RESULTS: Compared with the healthy control group, the levels of ST2 mRNA and serum in the peripheral blood of HCC patients increased (p < 0.05), while the levels of IL-33 mRNA and serum showed no significant difference between the two groups (p > 0.05). In the meta-analysis section, at the tissue level, the overall analysis showed that the expression of IL-33 was positively correlated with tumor stage, histological grade, distant metastasis, and tumor size. Compared with patients with low IL-33 expression, the 3-year overall survival (OS) rate (OR = 3.467, p < 0.001) and 5-year OS rate (OR = 2.784, p < 0.001) of patients with high IL-33 expression were lower. At the serum expression level, the overall analysis showed that the expression of IL-33 increased the risk of cancer, and the serum level of IL-33 was positively correlated with tumor stage and vascular invasion. CONCLUSION: IL-33/ST2 is a useful predictive or prognostic biomarker in clinical evaluation and may be used as a potential therapeutic target, but much research is needed to verify this hypothesis.

Relationship between vascular endothelial growth factor -2578C > a gene polymorphism and lung cancer risk: a meta-analysis.

BACKGROUND: Several reports were published on the relationship between the vascular endothelial growth factor (VEGF) -2578C > A gene polymorphism and lung cancer risk; however, the results are debatable. This meta-analysis was conducted to assess the relationship between VEGF -2578C > A gene polymorphism and lung cancer risk. METHODS: The associated literatures were identified on the 1st of September 2018 from CBM-disc (China Biological Medicine Database) and PubMed. RESULT: A total of 14 reports were recruited into our meta-analysis to assess the association between VEGF -2578C > A gene polymorphism and lung cancer susceptibility. There was a marked association between VEGF -2578C > A A allele / CC genotype and lung cancer risk in overall and Asian populations (overall populations: A allele: OR = 1.26, 95% CI: 1.08-1.46, P = 0.003; CC genotype: OR = 0.72, 95% CI: 0.54-0.95, P = 0.02; Asians: A allele: OR = 1.33, 95% CI: 1.15-1.55, P = 0.0002; CC genotype: OR = 0.68, 95% CI: 0.50-0.93, P = 0.01). However, VEGF -2578C > A gene polymorphism was not associated with the risk of lung cancer in Caucasians. CONCLUSION: VEGF -2578C > A A allele / CC genotype is associated with the lung cancer susceptibility in Asians and in overall populations.

Association of glutathione S-transferase P1 gene polymorphism with the risk of small-cell carcinoma of lung cancer.

The conclusions of the published reports on the relationship between glutathione S-transferase P1 (GSTP1) gene polymorphism and the risk of small-cell carcinoma of lung cancer are still debated. GSTP1 is one of the important mutant sites reported at present. This meta-analysis was performed to evaluate the association between GSTP1 and the risk of small-cell carcinoma of lung cancer. The association investigations were identified from PubMed and Cochrane Library, and eligible studies were included and synthesized using meta-analysis method. Ten reports were included into this meta-analysis for the association of GSTP1 A/G gene polymorphism and small-cell carcinoma of lung cancer. The G allele and GG genotype were not associated with the susceptibility of risk of small-cell carcinoma in overall populations, East-Asians and Turkish population. However, there was an association between GG genotype with the risk of small-cell carcinoma in Caucasians. In conclusion, GG genotype was associated with the risk of small-cell carcinoma in Caucasian patients with lung cancer. However, GSTP1 A/G gene polymorphism is not associated with the susceptibility of small-cell carcinoma in overall populations, East-Asians and Turkish population.

Association of vitamin D receptor BsmI gene polymorphism with the risk of type 2 diabetes mellitus.

Relationship between vitamin D receptor (VDR) BsmI (rs1544410) gene polymorphism and the type 2 diabetes mellitus (T2DM) susceptibility is still conflicting at present. This meta-analysis was conducted to assess the association between VDR BsmI gene polymorphism and the risk of T2DM. The association studies were identified from PubMed, and Cochrane Library on 1 January 2014, and eligible investigations were included and synthesized using meta-analysis method. Eleven reports were recruited into this meta-analysis for the association of VDR BsmI gene polymorphism with T2DM susceptibility. In overall populations, B allele, BB genotype and bb genotype were not associated with T2DM risk. VDR BsmI gene polymorphism was also not associated with the T2DM risk in Asians and Caucasians. In conclusion, VDR BsmI gene polymorphism was also not associated with T2DM risk in overall populations, Asians and Caucasians. However, more studies should be conducted to confirm it.

Association of vitamin D receptor gene polymorphism with the risk of renal cell carcinoma: a meta-analysis.

Relationship between vitamin D receptor (VDR) gene polymorphism and the risk of renal cell carcinoma from the published reports are still conflicting. This study was conducted to evaluate the relationship between VDR ApaI (rs7975232), BsmI (rs1544410), TaqI (rs731236), and Fok1 (rs2228570) gene polymorphism and the risk of renal cell carcinoma using meta-analysis method. The association studies were identified from PubMed, and Cochrane Library on 1 March 2014, and eligible investigations were included and synthesized using meta-analysis method. Five reports were recruited into this meta-analysis for the association of VDR gene polymorphism with renal cell carcinoma susceptibility. In this meta-analysis, the ApaI AA genotype, BsmI BB genotype, Fok1 f allele, and Fok1 FF genotype were associated with the risk of renal cell carcinoma in Asians. However, VDR ApaI, BsmI, TaqI, and Fok1 gene polymorphism were not associated with the risk of renal cell carcinoma in overall populations and in Caucasians. In conclusion, the ApaI AA genotype, BsmI BB genotype, Fok1 f allele, and Fok1 FF genotype were associated with the risk of renal cell carcinoma in Asians. However, more studies should be conducted to confirm it.

Clinical correlations of motor and somatosensory evoked potentials in neuromyelitis optica.

BACKGROUND: Motor and somatosensory evoked potentials (MEPs and SSEPs) are sensitive tools for detecting subclinical lesions, assessing disease severity, and determining the prognosis for outcomes of patients with inflammatory neurological diseases such as multiple sclerosis. However, their roles in neuromyelitis optica (NMO), a severe inflammatory neurological disease that predominantly involves optic nerves and spinal cord, have not yet been clarified. METHODS AND FINDINGS: Clinical symptoms and examination findings at relapses of 30 NMO patients were retrospectively reviewed. Abnormal MEPs were observed in 69.2% of patients. Patients with abnormal motor central conduction time (CCT) of the lower limbs had higher Kurtzke Expanded Disability Status Scale (EDSS) scores than those with normal responses (P = 0.027). Abnormal SSEPs were found in 69.0% of patients. Patients with abnormal lower limb sensory CCT had higher EDSS scores than those with normal responses (P = 0.019). In 28 patients followed up more than 6 months, only one of 11 patients (9.1%) with normal SSEPs of the lower limbs had new relapses within 6 months, whereas 8 of 17 patients (47.1%, P = 0.049) with abnormal SSEPs of the lower limbs had new relapses. CONCLUSIONS: These results indicate MEPs and SSEPs of the lower limbs are good indicators for the disability status at relapses of NMO. Lower limb SSEPs may be a good tool for reflecting the frequency of relapses of NMO.
